First feedback to Saber bhai is to please make age-based cricket 2-day. 90 overs max for 1st innings. Batting points and bowling points.
Second would be to put in one decent sized play-field in every high-density population area. Explore astro-turf + rolled gravel wickets for ease of maintenance.
Third is dream up a indo-pak-sl-bd 1st class tourney. 4 teams from India. 2 from Pakistan. 1 each from BD & Sri-Lanka. Set up a Shield cricket like Champions league with them and market the heck out of it. This would become THE premier first class league in the world just like IPL has become the premiere 20/20 league.
Fourth - make peace with the two ladies who have Bangladesh as their birthright. Nothing can be done without their blessing anyway.
